2010-08-02Driver: Never try to use piped inputs.Daniel Dunbar

2010-08-02Driver: Start ripping out support for -pipe, which is worthless and complicatesDaniel Dunbar
too many other things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110007 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-19Driver: Change the driver to take the path to the main executable, instead ofDaniel Dunbar
taking it in pieces. - Fixes a problem where the Clang executable path was not initialized properly on Win32, because sys::Path::getBasename() doesn't do what I always think it does. Imagine that, a sys::Path interface that is confusing! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108667 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-14Driver: When re'execing clang, use path to the main executable instead ofDaniel Dunbar
looking up Clang in the normal search paths (which may end up finding the wrong clang). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108346 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-14Driver: Dissect -Wl, and -Xlinker arguments to remove --no-demangle, which was aDaniel Dunbar

2010-06-11Driver: Add an explicit argument translation phase to the driver itself. We ↵Daniel Dunbar
are going to need this to handle things like -Xassembler, -Xpreprocessor, and -Xlinker which we might have to introspect. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105842 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105762 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-07Driver: Support invoking Clang on .ll or .bc inputs.Daniel Dunbar
- We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o'). It is now possible to do something like: $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ... $ clang -c t.ll -o t.o ... assorted other compile flags ... and expect that the output will be almost* identical to: $ clang -c t.c -o t.o ... assorted other compile flags ... because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend. *: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105584 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-04Driver/Darwin: Model dsymutil properly, as a separate action/tool kind which isDaniel Dunbar
added as the last output step, instead of just hacking it into the link step. - Among other things, this fixes dSYM generation when using multiple -arch options. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105475 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-22Driver: When printing a "command was signalled" type of diagnostic, use theDaniel Dunbar
short name of the tool in use, instead of the name of the action that created the command. The practical impact is we now get: clang: error: clang frontend command failed due to signal 6 (use -v to see invocation) instead of: clang: error: assembler command failed due to signal 6 (use -v to see invocation) when clang crashes on a job that uses the integrated assembler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104417 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-14Driver: Enable -integrated-as by default, at least for Darwin/x86 without ↵Daniel Dunbar
-static. - How else will we figure out what is broken, eh? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103759 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-05add a new --print-diagnostic-categories option, which causes the driver toChris Lattner
print out all of the category numbers with their description. This is useful for clients that want to map the numbers produced by --fdiagnostics-show-category=id to their human readable string form. The output is simple but utilitarian: $ clang --print-diagnostic-categories 1,Format String 2,Something Else This implements rdar://7928193 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103080 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-06Driver: Add a Tool::hasGoodDiagnostics hook, and use it to simplify logic forDaniel Dunbar
deciding when we need to emit an extra "command failed" diagnostic. - This also fixes the case where we were emitting that extra diagnostics, even when using clang w/ the integrated assembler, which has good diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100529 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-01Driver: Add support for a CLANGXX_IS_PRODUCTION build variable, which enableDaniel Dunbar
Clang++ support, even in "Production" mode (for testing purposes). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100119 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-22Add very limited support for GCC's '-B' flag. This allows us to support unusualChandler Carruth
toolchain configurations and is a small step toward FreeBSD support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99159 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-20Driver: Support CC_PRINT_OPTIONS, used for logging the compile commands (in ↵Daniel Dunbar
-v style) to a file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99054 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-17PR5803: clang++: Treat untyped 'C' inputs as C++.Daniel Dunbar
- Patch by Andrzej K. Haczewski, with a tweak by me to emit a 'deprecated' diagnostic when we do this. We'll see what zee users say. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96511 91177308-0d34-0410-b5e6-96231b3b80d8

libBasic/Version.cpp, getClangFullVendorVersion(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94235 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22(1) Rename getClangSubversionRevision() to getClangRevision(), andTed Kremenek
have it return a StringRef instead of an integer (to be more VCS agnostic). (2) Add getClangFullRepositoryVersion(), which contains an amalgamation of the repository name and the revision. (3) Change PCH to only emit the string returned by getClangFullRepositoryVersion() instead of also emitting the value of getClangSubversionRevision() (which has been removed). This is functionally equivalent. More cleanup to version string generation pending... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94231 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-22Driver: When linking, don't warn about unused arguments which are obviously onlyDaniel Dunbar
used during compilation. - There is no easy way to define this group properly, unfortunately, and maybe this is a losing strategy. For now this is unambiguous more friendly, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91940 91177308-0d34-0410-b5e6-96231b3b80d8
